[分享]FRED如何调用Matlab [复制链接]

简介：FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图，本文的目的是通过运行一个案例来实现与Matlab的相互调用，在此我们需要借助脚本来完成，此脚本为视为通用型脚本。 k vue@  
[+:mt</HN  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： ]sm0E@1  
enableservice('AutomationServer', true) m&8U4uHN  
enableservice('AutomationServer') [`Qp;_K?t  
i SAidK
,  
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 l?yZtZ8

在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： Un8#f+odR  
1. 在FRED脚本编辑界面找到参考. NejsI un%  
2. 找到Matlab Automation Server Type Library DS[l

3. 将名字改为MLAPP YfrTvKX

在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 w7`@=kVx

1. 创建Matlab服务器。 =xlYQ}-(a  
2. 移动探测面对于前一聚焦面的位置。 9rf|r 3  
3. 在探测面追迹光线 oRvm*"8B  
4. 在探测面计算照度 dZ]\1""#H  
5. 使用PutWorkspaceData发送照度数据到Matlab kw-

6. 使用PutFullMatrix发送标量场数据到Matlab中 v#<+

7. 用Matlab画出照度数据 i-"h"nF"  
8. 在Matlab计算照度平均值 YiI:uG!|D  
9. 返回数据到FRED中 [pC-{~
